Quite a few things going on ;) First of all, CMake 2.6.4 has been released, with a bunch of bugfixes. Just tried it, no problems so far. The other major new release is Boost 1.39, which is now fully in the 3-month release cycle. In my opinion, this is the best thing that could happen for Boost, as we — the users — can be sure that a fixed bug will be pushed out no later than in 3 months. It adds the header-only, thread-safe signals2 library, which I’m going to try out really soon. The build system has not been changed, so you can still use my old build instructions to get a customized x86 & x64 build.
